IMPROVEMENT IN BRICK-KILNS.

Specication forming part of Letters Patent No. 195,895, dated October 9,1877; application filed February 22, 1877.

To all whom 'it may concern:

Be it known that I, J EHIEL H. KELLEY, of Mmcie, in the county ofDelaware and State of Indiana, have invented certain new and usefulImprovements in Brick-Kilns and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, which form part of this specification.

The nature of my invention consists in the construction 'and arrangementof a kiln for burning brick, lime, tiling, &c., as will be hereinaftermore fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a sideelevation of my kiln. Fig. 2 is a transverse verticalsection of the same. Fig. 3 is a horizontal section through one of thefurnaces.

A represents the kiln proper, in which the articles to be burned areplaced. This kiln may be made of any suitable dimensions, and is on theoutside, along two opposite sides, provided with furnaces B B,extending` the entire length of the kiln. Each furnace or fire-arch Bcommunicates with the interior of the kiln A by a series of apertures, aa, corresponding in number with the arches of the kiln, and each furnaceor fire-arch has a suitable number of fire-doors, C. In a twelve-archkiln only three of these fire-doors on each side are needed. d d aresuitable draft-openings into the fire-arch or furnace B, at suitabledistances apart, and located between the firedoors O, as well as nearthe ends of the furnace. Above each furnace is a series of draft- Iitenters the kiln.

openings, b, leading into the kiln, these draftopenings corresponding innumber and location with the arches a a, as shown. D is the grate of thefurnace, under whicl is the ash-pit E. The bottom G of the ash-pitinclines outward and downward, thereby making the ash-pit self-cleaning,as the ashes will settle down and pass out through openings e, whichalso form draft-openings. The draft-openings b, d, and e are allprovided with suitable doors or dampers for regulating the variousdrafts, as may be desired.

By this construction of the kiln the operator has no cold air to contendwith, because the fire is all on the outside of the kil in thefirearches, and when the doors G are opened the air, rushing in, willall become heated before The operator can burn the fnuaces on botl sidesat the same time, and not, as in ordinary kilns, first one side and thenthe other. There are no coals in the kiln to shell or damage the brick.It saves labor, ime, and fuel, and the improvement can be attached toany brick, tile, or lime kiln.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination of the kiln A, the exterior fire-arches B B, witlopenings a and fire-doors C, the ash-pit E, witl inclined fioor G, andthe draft-openings b d e, all constructed and arranged substantially asand for the purposes herein set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
